What is it
Volume measures how much three-dimensional space a shape takes up — for simple shapes like cuboids, it's calculated by multiplying length × width × height.

Always double-check that all three measurements are in the same unit before multiplying — mixing centimetres and metres is one of the most common errors in volume questions.
